Background: Enhanced depth imaging (EDI) and spectral domain optical coherence tomography (SD-OCT) provide high-definition cross-sectional images of the choroid. Information on alterations in choroidal thickness (CT) after laser photocoagulation (LC) in aggressive posterior retinopathy of prematurity (APROP) and threshold disease (TD) is rare., Patients and Methods: A total of 75 eyes were retrospectively analyzed in 4 groups. Groups 1 and 2 included patients with APROP and TD, respectively, who underwent LC. Group 3 included ROP children who did not undergo LC and group 4 included full-term children. Infants aged ≥4 < 7, who had examination of subfoveal (SF) CT with SD-EDI-OCT, visual acuity (VA), spherical equivalent (SE), anterior segment and fundus examination, axial lenght (AXL) were included. The results of SFCT, VA and SE at the age of ≥ 4 < 7 years, AXL, gestational age (GA), birth weight (BW) and age at examination were compared between the groups. Potential risk factors (GA, BW, SE, AXL and SFCT) influencing visual acuity were evaluated by using multivariate linear regression analysis., Results: The results of SFCT and AXL were not significantly different between groups 2 and 3 or between groups 3 and 4. There was a significant difference between the other groups for SFCT and AXL and VA was significantly different between all groups. The SE was not significantly different between groups 3 and 4 but there was a significant difference for SE, BW and GA between the groups. Age at examination was not significantly different between the groups. Multivariate linear regression analysis revealed SFCT for groups 1 and 2, GA for group 3 and GA, SFCT and AXL for group 4 as independent risk factors influencing visual acuity., Conclusion: The regression model used for groups 1-4 explains the variation of the dependent risk factor LogMar VA for groups 1-4 with 31.2 %, 43.5 %, 9.6 % and 69.4 %, respectively. These values expressed in percentage demonstrate that even more predictors may influence the dependent factor LogMar VA than evaluated in the study.

Purpose: To investigate the indocyanine green (ICG) angiographic findings of healed traumatic choroidal ruptures., Methods: Three eyes of two patients with choroidal ruptures underwent both fluorescein angiography and ICG angiography with a digital high-resolution system., Results: Fundus examination showed healed choroidal ruptures in all three eyes. Two of the eyes had old macular scars and one eye had a recent choroidal neovascular membrane with serous detachment of the macula. On fluorescein angiography, the choroidal ruptures showed hypofluorescence at very early stages followed by late hyperfluorescence. On ICG angiography, the choroidal ruptures were hypofluorescent in early, mid and late phases. ICG angiography provided a clear delineation of the choroidal ruptures. In all eyes, the lesion was better defined on the ICG angiogram than on the fluorescein angiogram., Conclusions: ICG angiography can be helpful in the clinical evaluation of choroidal ruptures and can be used together with fluorescein angiography for the diagnosis and follow-up of choroidal ruptures.
